Remove DW_SIGNATURE
This removes DW_SIGNATURE in favor of methods on struct attribute. As usual, the methods check the form, which DW_SIGNATURE did not do. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_attribute_value, lookup_die_type) (dump_die_shallow, follow_die_sig, get_DW_AT_signature_type): Update. * dwarf2/attribute.h (struct attribute) <as_signature, set_signature>: New methods. (DW_SIGNATURE): Remove.
